63006: Could not format given content for the channel. Please see Channel specific error message for more information

Twilio returns 63006 when it cannot format the content you sent for the selected channel. Review the channel-specific error message in the message logs to find the exact formatting issue, and compare your template against Twilio's channel support and content-template rules. Twilio sends the most complex translation supported by the chosen channel, and some content components can still be incompatible across channels.

• The content template includes a type or component that the destination channel does not support.
• The template includes multiple content types, and Twilio cannot translate the message into a format the selected channel supports.
• Variable values, names, or URL samples do not follow Content Template rules, so Twilio cannot render the final message correctly.

• Check the channel support table and send a content type that the destination channel supports.
• Remove or replace any unsupported components, then resend the message with a translation that matches the target channel.
• Validate your variable names, counts, and values, and make sure any URL path samples resolve to publicly hosted media or URL samples.
• Open the message error details in Twilio Console and use the channel-specific error message to pinpoint the formatting problem.
